On said shaft 17 are shown two differently sized sprocket gear I8, 19, one of which is selectively used to transmit motion by means of a sprocket chain 6 to the feed shaft 3.

' The frame A is hinged to the axle B and is suspended at an angle to the feed shaft 3 by means of a tie-bar 20. This tie-bar is made of two sections adjustably connected together. 21 represents the forward end of said sectional bar. which is provided with a boss 22, in which is journaled the hub 23 of sprocket gear 5, which hub is provided with a square orifice fitting shaft 3, so as to allow the tie-bar to turn on the hub of the s rocket wheel when said tie-bar is adjusted. he forward end of the tie-bar 20 is rigidly connected to the sleeve of the front section by a set screw 25. The rear end of said tie-bar projects through a boss 2 formed on sleeve '27, supported upon the frame A. Said tie-bar suspends the frame and its contained parts u )on the axlg B, at an angle to the rod 3 o the feed devices. This change of angle is accomplished by lengthening or shortening the tie-bar to the desired angle of adjustment.

It will thus be seen that we employ two independent systems of change gears. The primary variation of speed is accmnpiisln-d by changing the position of spungear 7. relative to the primary transmitter i". without changing the angle of inclination of the frame. The second change of speeds is effected by loosening the rod 2" so as to swing the frame to change the distance between shaft 17 and shaft 3. then shifting the sprocket chain from thc wheels 5. l!) to the sprocket wheels 4. 1 a! l tightening the rod 20 to secure this new ustmcnt. Each of the speed changes effect \c through the variable gcar me hanism on the hinged frmne will then have a new feed value by reason of the different ratios of the sprmkct wheels 4, 18, as compared to the ratio of the wheels 5, 1!). Thus a vcr' large range of speed changes may be 0 itained employing the bracket frame and its train of gears as the primary system of transmission and multiplying the same by the secondary system of transmission.

By means of the tie-bar 20, the taulncss of the sprocket chain can be regulated at will.

Vl'hile the drawings show the frame A projected rcarwardly from the axle B. it is obvious that it can be projected toward the front of the implement. This mechanism can be readily attached to any type of seeding machine, r gardless of the variations df the distance between the driving axlr and the feed rod of any of said dill'crent types of implements.

The attachment frame is of yoke or U form in the general plan and the transmission gears are mounted upon shafts jun!" na led directly to and between the arms of said frame. so that the frame itsclf is ofbrace form andfirmly holds the said parts in worl ing position, as well as allowing the said frame and its contained gears to be attached to or moved bodily from the seed.
